COMBINATION LIQUID-LOCK FOR AUTOMOBILES.

To all whom t may concern.'

Be it known that I, Nici-roms l-l. WIRTZ, a citizen of the UnitedStates, residing at lVatertown, in the county of Codington and State ofSouth Dakota, have invented a new and useful Combination Liquid-Lock forAutomobiles, of which the following is a specification.

This invention relates to valves, but more particularly to a combinationor permuta tion valve having for its object to close the flow of liquidfrom its source of supply and the invention has particular and specialapplication to a gasolene or other fluid valve for automobile motors andother internal combustion motors whereby the motor may be effectuallylocked against starting or continuous operation by the will `of the operator, in such manner that the motor can not be surreptitiously startedor operated.

With this object in view the invention consists in the novelconstruction and arrange# ment of the valve and particularly in theconstruction and arrangement of the axially movable fluid passageclosures in combination with the permanent or stationaryV members withwhich the axially movable closures coaet.

The invention also consists in certain other novel details ofconstruction and in certain combinations of parts, all of which will befirst fully described and afterward specifically pointed out in theappended claims. y

Referring to the accompanying drawings- Figure l is a vertical sectionalview through a valve constructed in accordance with this invention, and

Fig. 2 is a top plan view of the same.

Like numerals of reference indicate the same parts throughout the twofigures, in whichl indicates an annular substantially ringshaped memberhaving a gasolene or other fluid port or passage l to which the sourceof liquid supply is piped in any approved manner. The said annularmember l is provided with an annular recess 2 in which a. sleeve 2 isthreaded as shown in Fig. l, the said sleeve 2 having formed thereon atits upper end a dislrshaped portion 3 of a formation as shown in Fig. 1,said dish-shaped portion 3 terminating in a iiange 3.

Threaded on the bottom ,portion of the annular ring-shaped member' l isa substantially funnelshaped member 1l having Specification of LettersPatent. Tatami-,i3d @@pt, 11119 :E191 3Q Appli-cation led` November 14,1916. i

threaded connection 4c for the fuel or liquid line, it being understoodthat this valve is interposed at a convenient position in the fuel orliquid line and between the source of supply of the fuel or liquid andthe ultimate liquid or fuel receiving or dispensing apparatus, which ininternal combustion engines would be a carbureter or other air and gasmixing device.

Disposed internally of the annular ringshaped member l is a sleeve 8having formed on its lower end a flange 8 to be permanently connected tothe annular ringshaped member l by means of fastenings 19.

Disposed internally of the annular ringshaped member l and within thesleeve S is a similar sleeve l2, itself having on its bottom a flange l2lying on and against the flange 8 and permanently fastened to theannular ring-shaped member l by the common fas tenings 19.

It will be observed from Fig. l that each of the permanent andstationary sleeves S and l2 are provided with fuel apertures 9 and l0which fuel apertures 9 and 10 are disposed in line with the fuel orliquid passage or port l in the annular ring-shaped member l, and itwill also be seen from Fig. l that the sleeve 8 is of such externaldiameter as to provide an annular space be tween the sleeve 8 and theannular ringshaped member l, while the sleeve 12 is ofsuch externaldiameter as to provide an annular space between the sleeve l2 and thesleeve 8. From this construction it will be understood that the annularring-shaped member' l, the outer sleeve 2, the sleeve 8 and the sleevel2 are stationary and rigid with relation to the gas or fuel line.

Disposed within the outer sleeve 2 in the manner as shown in Fig. l isan axially movable sleeve or tubular member G terminating at its upperend in a fiange 7 and being of a thickness of wall to snugly enter thespace between the stationary sleeve S- and the annular ring-shapedmember' l, said sleeve or tubular member 6 being provided with a fuel orliquid aperture V6 for aline ment with the liquid or fuel port orpassage l in the annular ring-shaped member l, the flange 7 of saidsleeve or tubular member 6 being provided on its lower surface with adepending stop E for a purpose which will be presently described.

Disposed within the axially movable sleeve or tubular member 6 is asimilar axially movable sleeve or tubular memberl 10, itself beingprovided at its upper end with a flange 11 and being of a thickness oflwall to snugly enter the space between the two stationary sleeves 8 and12, said sleeve or tubular member 10 being provided with a liquid orfluid aperture 20 for alinement with the liquid or fuel port' or passage1 in the annular ring-shaped memberl, and

also for alinement with the liquid or fuel 'apertures 6, 9 and 10heretofore referred to, the said flange 11 of the annular movlbeingequipped with nuts 18'and18 for securing the axially movable parts inproper, relative and operative position. The central tubularmember 1G isprovided witha liquid or fuel aperture 16 registering with lthe otherfluid or liquid apertures in the two stationary sleeves S and 12 andwith the two axially movable sleeves or tubular members G and l0 in themanner as shown inv Fig. 1. The top of the central tubular member 16 isprovided with a flat member 17 closing the said central tubular memberand upon the under-surface of said fiat member 17 is a stop A.

Extending horizontally from the dishshaped member 3 is a supportingplate le* through which the central tubular member 16 extends and uponthe upper face of the plate 14 is a stop B arranged in the path ofrotation of the stop A on the central plate member 17, while arranged onthe under-face of the supporting plate 14k is a stop C positioned in thepath of rotation of the stop D on the flangell of the axially movablesleeve or tubular member 10, while arranged on the dish-shaped member 3`is a stop F positioned in the path of rotation of the stop E on theflange 7 of the' axially movable sleeve or tubular member 6. From this1t will be understood that lthe stops B, C and F are stationary withrelation tothe device, while the stops A, D and E are movable with theaxially movable sleeve 0r tubular members 6, 10 and 1G.

Positioned between the several axially movable sleeves or tubularmembers are washers 5, 9, 13 and 15, so as to insure the proper relativeposition of the parts.

Referring to the flanges 7, 11 and 17 on the axially movable tubularmembers, reference is made to Fig. 2, wherein it will appear that saidflanges are provided around their peripheries with a series of points 7,11 and 17', the. points on all three of the flanges being lof equalnumber so that theyV may coincide one with the. other in the manner asshown in Fig. 2,. while 1 provide on the flange 3 of the dishshapedmember 3 an arrow 20', indicating a starting point from which thecombination is worked out. Having thus described the several parts oftheinvention, its-operation is as follows: Upon axial movement of thesleeve or tubular member 6 a predetermined distance, its fuel aperture 6will register with the fuel or'liquid port or passage 1 in the (an-""5,0nular ring-shaped member '1, while axial movement of the sleeve ortubular member.'

10 and the centrall tubularfmember 16 will likewise bring their liquidor fuelapertures 10, 16 to register with the-fuel apertures in thestationary sleeves S and 12 and with the fuel or liquid passage 1 in theannular ring-shaped member'l. lVhenV all of these fuel or liquidapertures, in the several axially movable tubular members andin theV twostationary sleeves, Vregister one `with the other in the manner. asshown in Fig. 1, the fuel passes freely through thevalve, as Awill beClearly apparent from 4an inspectionof: V the'accompanying` drawings.VWhenfhow- 95 ever,`one or more ofthe axially movable sleeves or tubularmembers 6,10, and 16 are moved axially, communication between the fuelport or passage 1 and the funnelshaped member 4 is cut off sothat'no'fuel lo@ or liquid `can pass from the source of `supi l plythrough the liquid or fuel line. 1 In order to establish the properYposition of each of the axially movable tubular membersia order toeffect 'communication xthrough the 105 line, each of the axiallymovablemembers is moved'to the right or 'to the left until all of the movablestops A, D and E are in engagement with and in contact with the threestationary stops B, C and F. It will belun- 11@ derstood that thestationary stops Bf()` and F absolutely limit the extent of axialmovement ofthe three axially movable tubular members and (that,therefore, the extent of movement' of any lone'o'f the 'three' '115tubular members is entirely independent of, and has no bearingv uponthemovement of its next orother tubular member. When, therefore, all of thetubular members arein locked position against the stationary stops '120B, C and F, it isonly necessary to movefrst one andthen the others ofthe tubular meinbers a icertain predetermined number of points fromthearrow'20in order to'establish the necessary ,communicationthroughl125 the valve. For instance, a movement of 'the axially movabletubular member '6 three points to the right of the arrow' 20, a movementof the intermediate axially movable4V member 10 five points to theright-"of the 4130 arrow 2O and a movement of the central axiallymovable tubular member 16 three points to the right of the arrow 20would bring their liquid or fuel apertures in proper alinement toestablish communication between the valves, while, of course, any othercombination could be made in order to insure a variation for each valveproduced. As a matter of fact it is only necessary to move the threeaxially movable members a certain predetermined distance from the arrow2O and then drill a hole through all of the axially movable members andthrough the two stationary sleeves 8 and 12 in order to produce anydesired combination of the Valve.

As before stated the movement of any one of the axially movable tubularmembers has no effect or bearing upon the movement of any other of thetubular members, for as will appear from the foregoing specication takenin connection with the accompanying drawings that there is interposedbetween the axially movable tubular members the two stationary sleeves 8and 12. Accidental or unintentional movement of any one of the axiallymovable tubular members is, therefore, eectually provided against, whichmakes it possible for the operator to quickly and without loss of time,produce the desired combination or extent of movement of the threeaxially movable tubular members.

Having thus fully described the invention it is apparent that the sameis susceptible to changes and variations in the design, arrangement orconstruction of the parts and I consider myself clearly entitled to allsuch modications as fall within the limit and scope of the appendedclaims.

What l claim as new and desire to secure by Letters Patent of the UnitedStates, is z- 1. A valve of the type described, including an outerstationary casing, a plurality of stationary sleeves within the casingand spaced apart from the casing and from each other, the said casingand the said sleeves being provided with passages through which liquidmay pass, said passages being in alinement one with the other, aplurality of independent axially movable tubular members within the saidcasing and disposed in close contact with the said plurality of sleeveswithin the said casing, each of said tubular members being provided withan aperture for the passage of liquid arranged in the same transverseplane as the aforemen tioned liquid passages, each of said tubularmembers being provided with means for manual manipulation, a stationarystop for each of said axially movable tubular members and a stop on eachof said axially movable tubular members for engagement with thestationary stop for each of the axially movable tubular members to limitthe axial movement of each of the axially movable tubular members, thewhole being arranged in such manner that upon axial movement of the saidaxially movable tubular members, the said apertures therein may bebrought into alinement with the liquid passages in the casing and in thesaid stationary sleeves to eect communication through the whole,substantially as described and for the purposes set forth.
